It’s a burning question New Yorkers ask every summer — which sunscreen should I use?

Memorial Day is almost here, and Consumer Reports offers some answers. It tested 19 top-selling sunscreens with SPFs ranging from 30 to 75+ for factors like how well they protect against UVA and UVB rays.

The testing organization rated two as best buys — a combination of price and performance — and also recommended five others. It panned three.

There’s a new wrinkle. The FDA is requiring new labeling and testing to be in place by mid-December — and this season you’ll see a mix of old and new labelson the shelves.

“The new FDA requirement means that sunscreens that claim broad-spectrum protection will have to prove that they also protect against UVA radiation, which causes aging of skin and contributes to skin cancer,’’ said Nicole Sarrubbo, a Consumer Reports associate editor.

UVB radiation causes sunburn.

Consumer Reports found that among the sunscreens it tested, “seven products were very good against UVA [and] were excellent against UVB, even after water immersion for 80 minutes.’’

The consumer-watchdog group rated as best buys two products, No-Ad with Aloe & Vitamin E SPF 45, a lotion costing 59 cents an ounce and Walgreens Continuous Spray Sport SPF 50, at $1.30 an ounce.

It rated as the very worst Hawaiian Tropic Sheer Touch Creme Lotion SPF 50 because it got the “worst possible score on UVA.’’

CR said the other two worst were Banana Boat Kids Tear-Free Sting-Free SPF 50 and Alba Botanica Natural Very Emollient Sunblock Sport SPF 45. Both did well on UVB but tanked on UVA protection.
